This allows them to define a maximum access time. In contrast, Ethernet devices get less bandwidth as devices are added to the same node, therefore, maximum latency times cannot be guaranteed. This is particularly a problem for highly loaded nodes, such as those carrying image data. Additionally, Ethernet is more difficult than USB to implement at the board level.

EtherCAT might be the next logical solution as more transducers are controlled by a single PC or a device based on PC architecture. Cool blogs, keep them coming :) Yes, USB has certainly helped a lot to realize complex PC based automation projects.

Maybe you can use a micro-mirror IC or perhaps there is a mechanical solution. It’s hard to visualize your application without a picture, but I’ve got a couple ideas.

We have the circuit board already designed, but the use of a low cost digital light switch would revolutize a large industry. So far the light source and reciever are costing 100 to 125 per source. If we could incorporate the tranciever in our circuit board or just start over with a simple stamp based system there is a lot of potential. I am not at liberty to discuss paticulars unitl I get clearance from my management. Thank you.

I've not used Ada. Is it possible to develop Ada applications that run on PC's? Sounds like an interesting book.

I am writing a textbook, "Building Parallel, Embedded, and Real-Time Applications with Ada", for Cambridge University Press. I use the control of temperature and pressure in a pressure cooker cooking mango chutney to illustrate how the introduction of multiple threads of control simplify the implementation of control algorithms.
